SEAM-PRESSING DEVICE.

SPECIFICATION forming part of Letters Patent No. $76,606, dated June 7,1892.

Application filed November 3, 1891. Serial No. 410,765. (No model.)

To all w/tom it may concern:

Be it known that I, JOHN E. BROWN, a citizen of the United States,residing at "SK ashington Court-House, in the county of Fayette andState of Ohio, have invented certain new and useful Improvements inSeam-Pressing Devices; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The object of this invention is to provide improved pressing orflattening devices for use more especially on that class of machinesdesigned to turn and press the scallops and seams of shoe-uppers. V.

The improvements consistin the construction and combination of partsherein described, and particularly pointed out in the claims.

In the accompanying drawings, forming a part of this specification,Figure l is a side view, partly in elevation and partly in section,illustrating an embodiment of my improvements; and Fig. 2 is a frontelevation, with parts of the turning mechanism broken away.

Like letters denote corresponding parts in the two figures of thedrawings.

Referring to said drawings, the letter A designates a table, upon whichis supported a bed plate B. Secured to the rear part of the bedplate isthe presser frame or standard O,while upon the front portion of saidbed-plate is fixed a horn or standard D, carrying the scallop or seamturning mechanism. Pivoted to the standard 0 is a lever O, which hasconnected with its upper end a forwardly-extending horizontal arm 0 Thefront portion of the arm is held and supported so as to be horizontallyreciprocable in suitable bearingsupon the top of the forwardlyprojecting part of the standard 0. A dependent end portion of this arm 0carries a presser-disk B of the seam compressing or flattening device.The other or stationary portion of the seampressing device consists of adisk or head D provided with a shank or rod on, held by means of a pin cin a screw-threaded tube or socket-piece p in the end of the standard 0.The threaded tube or socket-piece p is made with a flange m, and betweenthis flange and the disk or head D I propose to place an elasticpacking-ring m of rubber or other material, so that the disk or head Dwill yield should the material placed between the presser be so thick asto render it liable to be unduly crushed under the blows of the disk D.The fact that the socket-piece p is threaded permits the adj ustme'ntthereof for compressing seams of different thicknesses.

Upon the threaded socket-piece 19 turns a check-nut 12, having afinger-piece n, whereby the said socket-piece may be locked in anyposition to which it may be adjusted.

Pivoted upon the front of the standard 0 is a lever O, the upper arm ofwhich is connected by means of a link 0 with the lever C, while thelower arm is provided with a presser or beater, which acts against theadjustable disk or head seated in the standard 0. The stationary part ofthis seam-presser resembles that at the top of the standard 0, and it istherefore unnecessary to describe again the several parts of which it iscomposed.

Connected with the lower end of the lever O is a bar or link P.

Ashaft Q, provided with any suitable means for applying driving-powerthereto, is journaledhorizontally in the bed-plate, so that a crank-pinq on one end of said shaft may engage the forward end of the bar or linkP.

The operation of the machine is as follows: The rotation of the shaft Q,causes the link or bar P to reciprocate horizontally, thus rocking thelever O. This rocking of the lever O, as is obvious, causes thepresser-arm C to reciprocate, and with it the disk or hammer D. Therocking of this lever C also causes the link 0 to reciprocate, and withit the rocking of lever 0.

As the seams at some parts of an upper are thicker or heavier than atothers it is der able that pressers whose faces do not approach eachother with equal propinquity be provided. Hence I have added the secondpresser, the stationary face of which maybe adjusted to suit the seamsof diiferent thicknesses.

The subject-matter herein set forth is also IOG 1. In a seam pressing orflattening device, the combination, with a support or standard, of avibrating head or hammer, a stationary head or disk having a shankadapted to fit within a tube or socket-piece, the said tube or socket-piece constructed to receive the shank and provided with a flange, anelastic packing interposed between said flange and the stationary disk,and means for securing the said tube or socket-piece in differentadusted positions on the standard,substantially as shown and described.

2. In a seam pressing or flattening device, the support orstandardprovided with a screwthreaded socket, a vibrating head or hammer, astationary head or disk having" a shank adapted to fit within a tube orsocket-piece, the said tube or socket-piece constructed to receive theshank and com plementarily screw: threaded to engage the socket in thestandard, a flange on said tube, and an elastic packing interposedbetween the flange and stationary disk, in combination, substantially asshown and described.

3. The combination of the standard C, the lever O, fulcrumed in saidstandard, means for rocking the same, the stationary disk or head D thearm or bar 0 havinga beater or presser at one end and pivotallyconnected with the lever C at the other and supported and sliding insuitable bearings, so as to be reciprocable longitudinally with respectto itself upon said standard and the said bearings, substantially asshown.

In testimony whereof I aflix mysignaturc in presence of two Witnesses.
